//  DESCRIPTION:
//      This function reads the potmeter located at the SmartRF04EB using the ADC. The function only 
//      reads the 8 MSBs from the ADC. The ebAdcinit(ADC_POT) function must be called before this 
//      function can be called.
//
//  RETURN VALUE:
//      UINT8
//          8 bit sample from ADC
//-------------------------------------------------------------------------------------------------------
UINT8 ebReadPotentiometer(void) {

    // Sample the ADC
